throughout; their length as compared with their breadth is also very diffe- 
rent in different species. In many species the outer claw is toothless, or 
has but a couple of coarse teeth far apart, while the inner claw is finely 
and closely pectinated. The hairs of the claw-tufts are usually gradually 
dilated towards the extremity.

Type: Ælurops v-insignitus (CLERCK). 
To this genus, besides the typical species, I refer e. g. also Salti- 
cus fasciatus HAHN, both remarkable for the projecting edge of the forehead, 
which conceals the central eyes of the first row, when the cephalothorax 
is looked at perpendicularly from above. As the names Dia and Parthenia 
were both already appropriated before KocH applied them to the two sub- 
genera, that we here have united into one genus (vid. 36, 37), I have been 
obliged to form a new generic name for them. — The species of this and 
the genus immediately following appear to me to be the most highly deve- 
loped European forms in the whole family. They leap with extraordinary 
vigour. Their claws are long and sinuated: in El. v-insignitus © the claws 
of the 4^ pair of legs have, much in front of their middle, about 3 or 4 
large, sparse teeth, 7 about 6. On the 1* pair, the claws of which are 
much shorter and more uniformly curved, the teeth are still fewer in number, 
at least ing. The claw-tuft is continued as a scopula beneath a part of 
the tarsus of the 1* pair; and the hairs of it are, nearer the extremity, 
gradually dilated in the form of tongues.
